Abstract

This study is to investigate the effects of capsaicin with high-fat diet on tissue glycogen contents in exercise-trained rats. Forty male Sprague-Dawley rats were offered a high-fat diet for 2 wks in individual cages and were exercise-trained by a animal treadmill running throughout the experimental period. After 2 wks of the prefeeding with high-fat diet, the rats were divided into two group: high-fat diet group(CON)and high-fat diet + capsaicin(0.014%) group(CAP). The rats were killed by decapitation at 10 hr(rest), 1 hr and 2 hr after treadmill running(27m/min, 6$^{\circ}$). Body weight and epididymal adipose tissure weight were significantly lower in CAP than in CON, but soleus muscle weight was not different between the two groups. Glycogen contents in liver, soleus and gastrocnemius white muscles were significantly lower in CAP than in CON at rest, 1 hr and 2 hr (p<0.05). However, glycogen content in gastrocnemius red muscle was significantly higher in CAP compared with CON at 2 hr after the exercise(p<0.05). These results indicate that capsaicin intake with high-fat diet would decrease glycogen contents in liver and muscle, however, this effect on glycogen metabolism could be changed by muscle type.
